Nice to get more info on this Jose,
Today when I was at Uni some of my leture mates asked me about it (knowing I do paintballing) and I did not know it had even happened, so when people who are out of the sport can find it out before me it just shows how bad this can be for the sport.
And the only thing I can think a use of a £40 plastic marker could be used for would be to throw in the bin, since you can get a spyder for £75 new or much cheap 2nd hand, so whats the point in buying crap when you can buy better crap
